Masturbation (unisex). Not to be confused with Palmfrying, which is similar but NOT TALKING ABOUT THE ELEVATOR.

-"guys, I'm so embarrassed...my mom walked in on me today...PALMROASTING!" "oh man! What'd you do!?" "I just kept going..."
-"Palmroasting sons-a-bitches..." (said in your best Clint Eastwood impression)
-"I'M TALKIN ABOUT THE ELEVATOR!..."
-"I was palmroasting last night...I used too much vegetable oil and it ended up being palmfrying..."
